\footnotesize Notes: Estimates of the $\delta_\lambda$ parameters in Equation \eqref{eq:g4}. Bootstrap standard errors in parentheses. Age is normalized to be zero at 18 years old. Reference category is ``L'' for each unobserved type. We restrict the offer arrival probability to equal 1 for those who worked in the white-collar sector in the previous period.
